Application tiled August 2, 1907. Serial No. 386,692.

and exact description of the same, reference being had to the accompanying drawings, .forming a part ofthe specification, and to the reference characters marked thereon.

The present invention relates to eyeglasses of the type in which the nose guards are positioned by finger ieces or forwardly extending arms, and has or an object to prov ide a construction 'in which the lens attaching devices, or lens mounts, are separate lfrom the bridge.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being 4pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a front view of eyeglasses embodying my invention. Fig. 2 is a 1perspective view of one of the nose guar( s and the adjacent parts of the eyeglasses, and` Fig. 3 is a vertical section through one of 4the lens mounts showing adjacent parts.

In eyeglasses employing finger-piece noseguards as ordinarily constructed, it is necessary to provide a specially formed mounting for a person whose nose is not in the center ot his face, if the centers of the lenses are to aline nth the centers of the pupils of the eyes. With eyeglasses constructed in ac cordanee with this invention, the making of special mountings is rendered unnecessary for the reason that the nose guards arc se arate from the lens mounts and are securefFto the mounting in such a manner that lens mounts of different lengths may b eniployed. A further feature of this invention 1s the provision of finger-piece nose guards with attaching brackets adapting them for commercial forms of eyeglasses.

In the present embodiment of the invention the mounting comprises a support consisting of the lensmounts or attaching devices and aabridge, and a pair oi noseguards having their own attaching brackets.

The lens mounts or attaching devices may be of the common or commercial form, that is, a pair of perforated ears l secured by a screw 2 to the lenses A and connected by a lens bearing portion 3 from which extend the posts 4 having vertical seats 5 at their outer ends. The bridge 6 connects the lens mounts and may be of any style that is formed separately therefrom, in the present instance having vertically arranged attaching arms or ends 7 to fit in the seats 5.

The nose guards which are formed each with a forwardly extending operating arm and a rearwardly extending nose hearing portion 9, are mounted on the sup -ort so that the distance between them w1 not be affected by the employment of lens mounts dierent lengths. In the present embodiment they are separate from the bridge and are swingingly mounted on their own attaching brackets, each of which preferably consists of an upwardly extending or vertical perforated arm l0 iitting within a vertical seat 5, and carrying a vertical pivot 11 at its lower end, the nose guards being preferably held thereon by a head l2. The forwardly extending arm of each guard may bebent vertically as in an upward direction, at i3 to the horizontal plane of the lens mount and then extended outwardly at 14 in front of the latter so that the finger piece and the lens mount make but one line and are thus inconspicuous. This operating arm is also adapted for use on other types of finger-piece nose guards.

In order to position each nose Uuard, theie arc provided springs, each of which in this instance is coiled around the pivot at 15 so as to have a common axis therewith and is secured at one of its ends to the bracket as by beine passed through a perforation therein at 16, the other oi' its ends being secured to the rearwardly extending portion of the guard, as at 17.

A single fastener, as a screw 18, asses throuehthe perforated attaching brac 'et 10 and t irough an end of the bridge and securely hol( s these parts in the vertical seat,-

of a lens mount.

It is apparent that with this invention, if the centers of the lenses do not aline with the centers of the pupils, the replacing of the lens mounts by others of diilerent length will shift the lenses relatively to the eyes so as' to give the proper result. It is further to be noted that the construction of the guard permounts having vertical seats mits of its being manufactured separatel in order that they may be used with eyeglass niountings of other types.

claim -as my invention:

l. In an eyeglass mounting, the combination with a support comprising a pair of lens mounts having boxes at their inner ends, of a brid e having portions detachably secured in said oxes, brackets having portions secured in said boxes and each carrying a pivot lying in a plane with the proximate box transverse t0 the plane of the lenses held by the lens mounts, nose guards mounted to swing on said pivots and carrying upper and lower nose bearing portions, and springs separate from said nose bearing portions for positioning the guards.

2. In an eyeglass mounting, a bridge, lens receiving the ends of the bridge, nose guards having forwardly extending operating arms, and mounted to swing about vertical axes, brackets on which the nose guards are swingingl'y mounted, fitted in the vertical seats, and separate springs for moving the nose guards toward tne nose.

3. A-new article of manufacture connorisn ing a bracket having an eye adapting it for attachment'to an eyeglass mounting and carrying a` vertically arranged pivot pin, a nose guard mounted to swing on said pivot pin, and a sprin separate from the nose bearing portion of t e guard secured to the bracket and to the guard. y

4. The combination with a vertically extending attaching bracket having arneye carrying a vertically arranged pivot, of a nose guard mounted on forwardly eXtendin operating arm, an a spring surrounding t e pivot and having one `of its endssecured tothe bracket and the other of its ends secured to the nose guard.

5. The combination with a nose guard having an operating arm, of" an attaching l mount.

the pivot, and having a` seams bracket on which the arm is mounted to turn about a vertical axis, extending upwardly from the latter, and a sexarate spring for moving the guard toward t e nose. 1
